Allegra (fexofenadine) is a human antihistamine, and giving it to your cat could be harmful or even fatal.
Here's why it's important to seek professional help:
* Dosage: Human medications are formulated for humans, and giving the wrong dosage to a cat can be extremely dangerous.
* Side effects: Cats can react differently to medications than humans. Allegra could cause severe side effects in your cat, such as vomiting, diarrhea, lethargy, and even organ damage.
* Underlying conditions: Giving the wrong medication could mask symptoms of a serious underlying condition.
What to do:
1. Contact your veterinarian immediately. They can diagnose your cat's allergies and prescribe the appropriate medication.
2. Follow your veterinarian's instructions carefully. Don't give your cat any medication without their approval.
Please remember that your cat's health is important. Always consult a veterinarian for any medical issues.
